LEI – originally the Landbouw-Economisch Instituut (Agricultural Economics Institute) – was established in the late 1930s by agricultural organisations. In the 1970s it became part of the Dutch ministry of Agriculture and in the 1990s it was privatised.It became part of Wageningen University and Research Centre, within which it combined with the Department of Social Sciences to form the Social Sciences Group. It was renamed in 2016 to "Wageningen Economic Research" (abbreviated "WEcR", to differentiate it from
Wageningen Environmental Research, WENR). On 1 January 2025, WEcR merged with Wageningen Centre for Development Innovation to form Wageningen Social & Economic Research (WSER). Wageningen Centre for Development Innovation began its journey in 1951 as the International Agricultural Centre (IAC)—a pioneering initiative of the Dutch Ministry of Agriculture (LNV), created to support countries undergoing rapid development. Over the decades, IAC evolved through integration into Wageningen UR in 2001, becoming part of Wageningen International, and eventually launching as a separate business unit, Centre for Development Innovation, in 2009. With a focus on capacity strengthening, social learning, and complex system innovation, WCDI has grown into a key knowledge partner in global sustainable development. On 1 January 2025, WCDI merged with WEcR to form Wageningen Social & Economic Research (WSER). == See also ==
